2-Level-Wavelet-Based License Plate Edge Detection

Against well-known vertical Sobel operator adopted by most license plate detection (LPD) algorithms, this paper presents a robust and real-time method to enhance both edge density and intensity of license plates under various outdoor environments. The proposed method applies HL subband feature of 2D...
